The carrying a curved leaf spring abuttingpoints of engagementof toe vertical members against an inner wall of theselected frame with the horizontal members are predetermember and havinga tendency to press the mined by suitable markings and L-shaped studs orbolts through the frame members, rackets 3 secured to register withthese consequently when the studs or bolts carried points so that as faras possible each vertical ly a bar come opposite the stud or bolt holesframe member is secured between a pair of in a fi anie member they willproject through b k t 3 as how i Fi 3 a d 4,

such holes and registering holes in a bracket, Each bracket 3 isstrengthened by a f then being applied to secure the bracket. which canbe secured after the bracket has been brought to the requisite angle tofit snugly against the selected frame members 1 and 2. Templets can beemployed to obtain a proper location and angle of the brackets 3.

The brackets 3 are firmly secured to the frame members 1 and 2 by studs5 carried by metal bars 6 inserted in the frame members. The bars 6 havestud holes formed in them at points the same distance apart ascorresponding holes in the frame members and brackets so that by firstaffixing the studs 5 to the bars 6, the bars can be slid along theinterior of the frame members until the studs register with the studholes prepared in the frame members for them, and the studs pressed upthrough the holes in the frame members. This can be effected by engagingthe bar 6 in the end of a tube or holder and pushing the bar along theinterior of the frame member with the studs pressing against the side ofthe frame member having the stud holes. This pressure can be obtained byfitting to each bar 6 one or more curved leaf springs 7 adapted to ridewith a fair amount of pressure over the side of the frame memberopposite to the side containing the stud holes. The bar 6 may bepositioned laterally by the tube or holder in which it is engaged. Thisholder may have port-ions to engage the inner side faces of the boxsection members.

The bars 6 are preferably of segmental or semi-circular section, theirflat faces fitting against the walls of the frame members.

In practice the brackets are built up to a standard angle and shape andare then trued up accurately by grinding upon each face and upon one orboth sides. The stud holes are then drilled to templet or in a jig toensure accurate placing. This will ensure interchangeability, ease oferection and a correct fit of the parts against each other.

If desired, a roughened, grooved or serrated surface may be arrangedbetween the faces of the brackets and the frame members to increase thefriction between them and thus relieve the bolts of shearing stresses.This may be effected by using a thin strip of steel having a roughenedor serrated surface on both sides, which is inserted between the twofaces of the brackets and the frame members or the brackets or framemembers may themselves be so roughened or serrated.

As shown in Fig. 2, when a vehicle or other body frame has curved orpartially curved sides, the longitudinal frame members 1 can have theirouter sides shaped to be continuous with the vertical frame members, thebrackets 3 being shaped to fit flush against the frame members.

My invention is applicable to quite a large variety of vehicle and otherbodies, and is particularly suitable for the conventional form ofchassis for open or closed bodies of said elements.

JAMES MARTIN.
